Answer: -1/2
Explanation:
To find the slope: rise/run
starting from the point (0,2), you go up 1 to reach the line
Therefore 1 is your rise.
Then go right 2 units and you hit the line again.
Therefore the slope is 1/2.
But the linear line is going downwards, so it is a negative slope
Therefore your final answer is:
-1/2
